  abstract = {{L}and-use changes have been significant these last decades in {W}est {A}frica, particularly in the {S}ahel region; in this area, climatic and demographic factors have led to a rise in cropped areas in recent decades causing strong changes in the water cycle and in river regimes. {T}his study compares the rainfall-runoff relationships for two periods (1991-1994 and 2004-2011) in two small and similar neighbouring {S}ahelian catchments (approx 0.1 km(2) each). {T}his allows identification of the different hydrological consequences of land-use/land-cover change, particularly the fallow shortening and the consequent degradation of topsoil. {T}he main land surface change is a 75% increase in crusted soil area. {R}unoff increased by more than 20% on average between the two periods while flood duration decreased by 50% on average. {H}owever, runoff values remained largely constant in the lower part of the northern basin due to a strong increase in in-channel infiltration.},
